The invention discloses a method for quickly concentrating a pan-domain monitoring video based on spatial constraint, and relates to the technical field of video image processing methods. The method comprises the following steps: detecting a sensitive target crossing the boundary of a monitoring area by adopting a space-time slicing method; matching a target by adding boundary space information ofa monitoring area; and according to the spatial position information of the camera, constructing an overall background of the monitoring area, marking the target motion information, and constructinga ubiquitous area concentrated monitoring video. According to the method, the video can be efficiently concentrated, and the user can be helped to quickly obtain the motion process of the target.
Description
technical field [0001] The invention relates to the technical field of image processing methods, in particular to a method for quickly concentrating pan-domain surveillance video based on space constraints. Background technique [0002] Nowadays, with the rapid construction and development of smart cities, a single surveillance camera is no longer able to meet people's needs for a stable and safe life. The installation and use of cross-camera networks have spread across every corner of people's production and life. The continuous monitoring has produced a large number of surveillance videos. Different from traditional videos, these videos have the characteristics of large redundancy, fixed users, and no obvious camera transitions. How to store and browse massive cross-camera surveillance videos concisely and efficiently has an urgent practical demand. [0003] At present, many researchers have done a lot of research work on single-camera surveillance video enrichment. For...
